脱硫石膏-活性铝体系复合矿物掺合料的研制

The research of mineral admixture compound of desulfurization gypsum-active aluminum system

研究了脱硫石膏热激活工艺制度对脱硫石膏活性的影响;脱硫石膏复合矿物外加剂代替水泥的合适范围;脱硫石膏复合矿物外加剂胶砂理想的蒸养制度。结果表明:在蒸养温度为60℃中恒温6h胶凝体系反应到达最佳效果,脱硫石膏的处理温度对胶凝体系影响不大;脱硫石膏复合矿物外加剂代替水泥最佳量为50%～60%。

The paper studied the effect of heat treatment on the activity of the desulfurization gypsum;the appropriate areas that the compound mineral admixture instead of cement and the proper maintenance condition.It would be better that the sample is maintained in 60℃ for six hours,there is a little effect that the heat treatment impact on the activity of the desulfurization gypsum;it would have good effect that the compound mineral admixture instead of cement for 50%-60%.
